. Application filed October 12, 1905. Serial No. 282,866- I of theUnitedStates of America, and a resident of Cincinnati, county of Hamilton,State of Ohio, have invented certain new and useful Improvements inPresses for Printing Finished Pails, of which the following is aspecification.

My invention relates to improved mechanism for printing trade-marks andother matter upon the exterior of cans and buckets. l

' One of its objects is to provide mechanism which will print upon theexteriors of cans or buckets after the same are completed, therebyavoiding any liability to injure the printed matter by subsequentoperations.

Another object is to provide improved mechanism for transferring the inkfrom the type to the cans and insuring a uniform movement thereof.

Another object is to provide improved means for stopa ping and startingthe printing mechanism.

Another object is to provide improved mechanism for receiving andholding the can, or bucket during the operation.

' It further consists in certain details of form, combina- Fig. 5 is adetail of the ratchet wheel and pawl for lockat the sides of said disk.5 0

ing the impression transmitting cylinder its driving gear. Fig. 6 is anenlarged detail end View of the transmitting cylinder. Fig. 7 is adetail end view' .of one of the starting clutch member s. Fig. 8 is anenlarged detail viewof'the clutch releasing mechanism. Fig. 9 is an' endview of the bucket supporting drum. Fig; 10 isasection through the sameon line x. t of Fig. 9.

Fig. 11 is a view similar to Fig. 9 showing a 'modified form of drum orcylinder. Fig. 12 is a section through the same on line of Fig. 11.

In the accompanying drawings, A, represents the frame of the machine,the table, A, of which is provided with horizontal ways, or, upon whichtravels a frame, B, which carries a type-frame, b, which is clampedthereon by means of set-screws, bi This frame also carries an inkingdisk, b andcam plates, b

The frame, B, is provided on its underside with a rack, B, which isengaged by a gear, 0, on the shaft, 0, which shaft is journaled inbrackets, c, secured to the underside of the'table, A. On the shaft, c,-is also mounted a'gear, 0 which is engagedby a segmental gear, D. Thissegmental gear is reciproc'ated by means of a crank-arm, d, projectingfrom the hub of the segmental gear, apitman, d, and a crank-arm, dmounted on the shaft, E, by which mechanism the frame, B, is

reciprocated backward and forward upon the-ways, a,

of the table, A. 0 represents rollers carried by the shaft, 0, andsupporting the frame, B, at opposite sides of the gear, 0.

Mounted on the table, A, above the frame, B, are a pair of ink rolls, F,F. These rolls are permitted to yield upward by means of springsmounted'in the housings, f. The ink is spread upon'the disk, b and asthe disk passes beneath the rolls, F, F, the cams, b lift the rollsuntil they reach the central portion of the disk, I), when they areallowed to rest upon the face thereof and again lifted when the disk ismoved in the opposite direction. The rolls, then by contact with eachother, distribute the ink over their surfaces and also upon the face ofthe type in the type-frame, I). Also mounted upon the table, A, is asemi-cylindrical transfer plate, G, the shaft, g, of which carriesa'gear, g, which engages a rack, 9 mounted on the frame, B. The plate G,is faced by an elastic pad, G, which pad is secured at one edge of thesegment and is drawn over a shaft, or roller, 9 at the opposite edge,where-it is strained or locked in place by means of a ratchet wheel, gand pawl, 9 The gear, g, is loosely mounted upon 'the shaft, 9, andcarries a spring actuated pawl, 9 which engages a single-toothed wheel,9 rigidly mounted on the shaft. Thus, the gear, g, is free to rotate,While the cylinder, G, moves in one direction only, with a step by stepmovement through the engagement of the pawl, g, with the wheel, g thismovementbeing timed with the forward movement of the frame, B. 1

H, represents a shaft mounted in bearing, h, and carcans or buckets, aremounted to be printed. This correspond with the movement of the transfercylinder,,

G. Thus the impression from the type will be transferred to the face, G,of the cylinder, G, and from thence to the face of the can, which issupported on the cylindei, I, after, which the parts move to a positionso that the segment, G, is clearof the face of the bucket and the bucketmay be removed and a fresh one substituted. 1

, Where it is desired to print upon the face of a tapered bucket, Ipreferably employ a drum, I, of the form shown in Figs. 9 and 10, havinga segmental tapered face, i, to support that portion of the can to beprinted and a spring-arm, i, which serves to strain the bucket in placeupon the drum, I, and permits the same to be readily pushed into placeand removed.

Where it is desired to print upon cylindrical cans or buckets, or thosehaving a reduced neck, such as shown in Fig. 12, I preferably provide acylindrical drum, J, having a section, j, rigidly mounted on the shaft,H, and a movable or collapsible section, j, to perniit the straining orclamping and removal of the can or bucket. The movable section, j, maybe variously operated to effect the desired purpose.

As shown in Figs. 11 and 12, K represents a shaft mounted in bearings inears, j on the frame, j, and

provided with an eccentric portion, k, which engages the cars, 70, ofthe section, j, so that the partial rotation of shaft, K, serves toexpand or retract the movable section, 3. 7' represents bolts projectingfrom cars, is, through guide slots, 3' in cars, P. The adjustment ofsection 3', is preferably effected by means of a cross-arm, j carried bythe shaft, K. One end of this cross-arm is provided with a stud, k whichmay be conveniently grasped by hand to expand the section, 9" after thecan has been set in place and may be automatically thrown to retractsection, 9', by projecting arm, 70, carried by the bracket, h, theopposite end of the cross arm, k serving by engagement with the shaft,H, to limit the movement of the shaft, K.

The various operative parts are driven in the following manner: L, L,represent tight and loose pulleys on the main driving shaft, Z. Z,represents a gear on the shaft, Z, which in turn drives a gear, a,loosely mounted on the shaft, E. e, represents a clutch member carriedon the sleeve forming the hub of the gear, e, and is continuously.otated thereby. 0 represents a clutch member splined to the shaft, E,and normally pressed into engagement with the clutch member, e, by meansof coiled springs, e engaging recesses, e, in said clutch member, andalso in a collar, a e, represents a camgroove in the face of the clutchmember, e which is engaged by a stud, or pin, m, seated in the housing,In, and actuated by a spring, m to hold the pin, m, in the cam-groove, 6m represents a pin on the treadle or starting lever, M, which engagesthe collar, m at the lower end of the pin, in, so that the depression ofthe lever, M, by the foot of the operator, will force the pin, m, fromthe groove, e, and allow the spring, a, to force the clutch members, e,0?, into engagement with each other, causing the shaft, E, to revolve.As soon as the lever, M, is released, the pin, 17%, springs upward,entering the cam-groove, e, and upon passing the diagonal portionthereof, throws the clutch member, a,

towards the collar, 2 and stops the movement of the machine until thecan has been removed and another one substituted, when the lever, M, isagain depressed. 0 represents a cam carried by the clutch member, e,which is engaged by a roller, n, pivoted at the lower end of the lever,72/, which lever is pivoted at n to a bracket on the underside of thetable, A. The upper end n of the lever, 11/, serves as a pawl, or dog,to enter a notch, n, in the wheel, n rigidly mounted on the shaft, 9.Thus the movementof the cam, e", retracts the dog, a from the notch, n,of the wheel, n unlocking and permitting the revolution of the shaft, g,

' which is again locked as soon as the notch, it, comes into position toreceive the dog, 17?, which serves to insure that the shaft, g, and itstransfer cylinder, G, shall come to a stop always at the same position.The cam 0 is so shaped that it causes the pawl, 11. to engage the notch,n immediately after the end of the forward movement of the type plate,b, and just at the time it is making its return movement, so that thetransfer cylinder is always held in the same relative position to thetype-plate, to insure that the impression made by the type upon thetransfer cylinder shall always come at the same place.

The mechanism herein shown and described is capable of considerablemodification without departing from the principle of my invention.
